We had to take him in because the other dogs in the house had tape-worms so we took him so he didn't get them. They took him back and gave him the shot and I heard him scream, though at the time I didn't think it was him because he just never screams like that for shots plus I misunderstood and thought it was the banana liquid looking stuff, but that is apparently for roundworms. So they brought him out and we learned it was him and that he didn't like that shot very much.

When the lady brought him out I asked him to jump into my arms, which he refused to do. That is really strange, but then I leaned down to pat him and he screamed again and flinched away. It was all really strange honestly, but I just put it off as he was being a baby as there was no blood and I looked at the area and there was no cut or anything.

Well I was petting him tonight and felt a weird lump/scab. I looked closer at it with a light and it was a nickel size scab that looked sunken in in the middle and it was green and puss filled. It's really nasty and he's very sensitive about it. He will let me and David touch it (obviously with great pain), but he won't let anyone else near it without screaming.

We shaved all the hair around it and cleaned it out with some antibacterial stuff we had from a previous vet visit and put a wrap around it. We also gave him some of his doggy pain killers to help with the pain. I'm taking him to the vet first thing, but wanted to see if anyone has seen a reaction like this before?

It almost looks like a scab but it's really deep and sunken in. It's nasty. >_<
